Title: Improvements in automatic fire alarms
IPC: G08B17/04
Filed: 1928-05-25
Abstract: 310,682. Long worth, J. R., and Hirst, H. May 25, 1928. Alarms operated by expansion of liquids or solids. - A push - button type of switch for use in an electric circuit and modified to serve as a fire-alarm, comprises a base 3<b>, a support 3<c>, and a casing 2. A heat-sensitive device, such as a capsule 4, is connected at one side to a push button 6, and at the other to a ptuuger 12 sliding through a disc 11 and held outwardly by a spring 12a. The tension of the spring 12<a>, and consequently the temperature at which the alarm operates, is adjusted by adjusting the disc 11 within the support 3<c>.

Title: Improvements relating to direct current transmission systems of the step-by-step type
IPC: H04L13/04
Filed: 1946-05-21
Abstract: 612,245. Synchronous movements. WHALLEY, H., SHAND, G., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 21, 1946, No. 15371. [Class 40 (iii)] Automatic aligning equipment for a step-bystep transmission system of the kind in which, upon starting up, the transmitter and receiver are rotated until the receiver reaches a lining- up position, whereupon its motion is arrested and the transmission line broken until the transmitter reaches a corresponding lining-up position at which the restriction on the movement of the receiver is removed and the transmission line is again completed, is provided with an impulse-operated electric apparatus actuated when the receiver reaches its lining-up position and operating to reduce the speed of rotation of the transmitter for a time period sufficient to allow the lining-up operation to take place. As shown, the transmitter T driven by a motor M is connected over lines 1, 2, 3 to a receiver R which, for example, may be connected to a radar aerial whose motion is to be controlled by the transmitter T. The receiver R is coupled to a cam disc RL which in the lining-up position closes contacts RL1 operating a synchronizing relay SR by which the receiver is disconnected from the lines 1, 2, 3 and locked in position by direct current applied over the two upper contacts. The transmitter continues to rotate until its lining-up cam TL reaches its lining-up position at which it opens contacts TL1 by which the relay SR is released and the receiver R is reconnected to the transmission lines. The arrangement fails if the closure period for the contacts RL is insufficient for the operation of the relay SR. The impulse applied by the closure of the contacts RL1 causes a diode V1 to charge a condenser C1 which in conjunction with a resistance R1 biasses the grid of a valve V2 to operate for a period sufficient to operate a relay A which closes a holding circuit at A1. The opening of a contact A2 removes a negative bias from the grid of a valve V3 which operates a relay B opening at B1, the holding circuit of the relay A. At the operated contact A3, the speed of the transmitter and consequently that of the receiver is reduced so that a sufficient' closure time for the contacts RL1 is ensured. In an alternative arrangement, Fig. 3 (not shown), the output of the diode is fed to operate the non-conductive valve of a flip-flop arrangement cutting off the second valve which is normally conducting and which returns to its conducting state after an interval determined by a condenser resistance arrangement in its grid circuit. A relay included in the plate circuit of the second valve is normally energized, but its release by the operation of the first valve controls the arrangement to reduce the speed of the transmitter.

IPC: E06B9/40
Filed: 1927-06-10
Abstract: 295,098. Donaldson Manufacturing Co., Ltd., and Hadden, W. J. June 10, 1927. Roller blinds.-A roller blind has at each end a spring drum 24 for the operating cord 45, the drum having a ratchet connection to the roller for raising the blind, and returning to its original position on release of the operating cord, which is thereby retracted. The ratchet devices comprise pivoted pawls 30 on the cord drums and ratchet wheels 23 frictionally clutched to the blind roller. The blind is lowered by pulling on its central tassel 64, the cord drums being then held against rotation by engagement of their respective cord tassels with their housings, whereon the ratchet wheel clutches 21 slip and act as friction brakes. The inner end of the drum spring 33 is preferably connected to the fixed part of the casing by a ratchet device 75, 79, Fig. 10, in order that incorrect winding of the operating cord on assembly may not break the spring. A screwed sleeve 25 at each end provides means for adjusting the pressure on the ratchet wheel clutch device, and grub screws 57 lock the parts in position when adjusted. Eyes 61 on the blind rod run on guide cords 60 at the sides of the window. Specification 293,922 is referred to in the second Provisional Specification.

Abstract: 515,120. Piles. HILEY, A., and BRITISH STEEL PILING CO., Ltd. May 24, 1938, No. 15508. [Class 68 (ii)] In a method of forming concrete piles in situ, a wad of granular material such as sand is disposed upon the charge of concrete material deposited in the pile driving tube, the granular material having a sufficient moisture content to increase its bulk, and the tube is then vibrated to deposit and tamp the concrete. The diameter of the finished column can be made larger than the diameter of the tube. The tube 1, Fig. 1, is filled, after driving tc the required depth, with concrete and is then oscillated by y upward and downward blows of a hammer 2 while being extracted for a distance depending upon the depth of the lower firm ground 3. An additional charge 9 of concrete is then placed in the tube and carried by damp sand 8, as shown in Fig 7, the extraction of the tube being resumd by upward blow only. Part of the sand may be contained in a bag. To expand the foot of the pile the tube together with a sand plug may be driven down through the concrete, the end of the tube being closed as described in Specifications 197,430, [Class 68 (ii)], and 385,647.

Abstract: 308,516. Marks, E. C. R., (Titanium, Ltd.). May 29, 1928. Alkaline-earth titanates, for instance barium titanate, for use particularly as pigments, are produced by heating precipitated titanium hydrate free from sulphate with alkaline-earth metal carbonates in the presence of an accelerator such as hydrochloric acid or an alkaline-earth metal chloride. Temperatures of 750-880‹ C. suffice for the reaction, and the proportions used may be such that the titanate produced is slightly alkaline. The titanium hydrate used may be freed from sulphate by treatment with a normal acetate of zinc, an alkali metal, or ammonium, followed by washing with water.
